A precise determination of in quenched QCD
P. Dimopoulos, J. Heitger, F. Palombi +3
The parameter is computed in quenched lattice QCD with Wilson twisted mass fermions. Two variants of tmQCD are used; in both of them the relevant four-fermion operat…
Split extended supersymmetry from intersecting branes
I. Antoniadis, K. Benakli, A. Delgado +2
We study string realizations of split extended supersymmetry, recently proposed in hep-ph/0507192. Supersymmetry is broken by small () deformations of intersection angles of …
Planar Quantum Mechanics: an Intriguing Supersymmetric Example
G. Veneziano, J. Wosiek
After setting up a Hamiltonian formulation of planar (matrix) quantum mechanics, we illustrate its effectiveness in a non-trivial supersymmetric example. The numerical and analytic…
First Measurement of Charged Current Cross Sections at HERA with Longitudinally Polarised Positrons
H1 Collaboration
Data taken with positrons of different longitudinal polarisation states in collision with unpolarised protons at HERA are used to measure the total cross sections of the charged cu…
The first-level trigger of ATLAS
Johannes Haller
Due to the huge interaction rates and the tough experimental environment of pp collisions at a centre-of-mass energy sqrt(s)=14TeV and luminosities of up to 10^34 cm^-2 s^-1, one o…
Flowing to four dimensions
E. Dudas, C. Papineau, V. A. Rubakov
We analyze the properties of a model with four-dimensional brane-localized Higgs type potential of a six dimensional scalar field satisfying the Dirichlet boundary condition on the…
CP Violation in the B System: Status and Perspectives
Robert Fleischer
In this decade, the exploration of CP violation is governed by the B-meson system, where non-leptonic decays play an outstanding role. To set the stage, we have first a look at the…
Search for Gauginos and Gauge Mediated SUSY Breaking Scenarios at LEP
Gabriella Pasztor
Data collected by the OPAL detector at LEP up to the highest energies of 209 GeV are analyzed to search for evidence of supersymmetric (SUSY) particle production. Chargino pair-pro…
Performance of ALICE pixel prototypes in high energy beams
D. Elia
The two innermost layers of the ALICE inner tracking system are instrumented with silicon pixel detectors. Single chip assembly prototypes of the ALICE pixels have been tested in h…
Observable (?) cosmological signatures of superstrings in pre-big bang models of inflation
M. Gasperini, S. Nicotri
The different couplings of the dilaton to the U(1) gauge field of heterotic and Type I superstrings may leave an imprint on the relics of the very early cosmological evolution. Wor…
Highlights of the B-Physics Landscape
Robert Fleischer
The exploration of the quark-flavour sector of the Standard Model is one of the hot topics in particle physics of this decade. In these studies, which show a fruitful interplay bet…
New Aspects of B -> pi pi, pi K and their Implications for Rare Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
We analyse the B -> pi pi, pi K modes in the light of the most recent B-factory data, and obtain the following new results: (i) the B0 -> pi+ pi-, pi- K+ modes prefer gamma=(74+-6)…
Discovery Potential of MSSM Higgs Bosons with ATLAS
Johannes Haller
In this article the potential of the ATLAS experiment to discover MSSM Higgs bosons is discussed. Various Monte-Carlo studies for SM Higgs boson production and dedicated MSSM Higgs…
The Full Second-Order Radiation Transfer Function for Large-Scale CMB Anisotropies
N. Bartolo, S. Matarrese, A. Riotto
We calculate the full second-order radiation transfer function for Cosmic Microwave Background anisotropies on large angular scales in a flat universe filled with matter and cosmol…
Stability of lattice QCD simulations and the thermodynamic limit
L. Del Debbio, L. Giusti, M. Lüscher +2
We study the spectral gap of the Wilson--Dirac operator in two-flavour lattice QCD as a function of the lattice spacing , the space-time volume and the current-quark mass $m…
On supersymmetry and other properties of a class of marginally deformed backgrounds
Rafael Hernandez, Konstadinos Sfetsos, Dimitrios Zoakos
We summarize our recent work on supergravity backgrounds dual to part of the Coulomb branch of N=1 theories constructed as marginal deformations of N=4 Yang-Mills. In particular, w…
Sliding Rings and Spinning Holes
Iosif Bena, Chih-Wei Wang, Nicholas P. Warner
We construct smooth supergravity solutions describing a BPS black ring with a BPS black hole centered at an arbitrary distance above the ring. We find that as one moves the black h…
The Physics of Extra Dimensions
I. Antoniadis
Lowering the string scale in the TeV region provides a theoretical framework for solving the mass hierarchy problem and unifying all interactions. The apparent weakness of gravity…
Beam test results of the irradiated Silicon Drift Detector for ALICE
S. Kushpil, E. Crescio, P. Giubellino +16
The Silicon Drift Detectors will equip two of the six cylindrical layers of high precision position sensitive detectors in the ITS of the ALICE experiment at LHC. In this paper we…
Supersymmetry Parameter Analysis: SPA Convention and Project
J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…
Supersymmetric completion of M-theory 4D-gauge algebra from twisted tori and fluxes
Riccardo D'Auria, Sergio Ferrara, Mario Trigiante
We present the supersymmetric completion of the M-theory free differential algebra resulting from a compactification to four dimensions on a twisted seven-torus with 4-form and 7-f…
Leptonic and charged kaon decay modes of the meson measured in heavy-ion collisions at the CERN SPS
D. Adamova, CERES Collaboration
We report a measurement of meson production in central Pb+Au collisions at E/A=158 GeV. For the first time in heavy-ion collisions, mesons were reconstructed in the…
